A separation welding device for the sectional joining and sectional separation of weldable film layers includes a temperature-controlled working surface that is designed to support joinable and separable film layers and further includes an electrical heating device as well as a counterholder for sectionally applying pressure to the joinable and separable film layers, which delimits a variably adjustable working gap with the working surface and that includes two mutually spaced joining stamps and one separating stamp arranged between the joining stamps wherein the separating stamp and/or at least one joining stamp is moveably attached to the counterholder wherein provision can be made for the separating stamp and/or the joining stamp to each be assigned a force sensor and/or a motion sensor to calculate a separation sequence determined by the separating stamp and/or a joining sequence determined by the joining stamp.

Separation welding device and method for the sectional joining and sectional separating of weldable film layers using a separation welding device

An apparatus is provided for joining together substrates, which have an inner hole, to form a substrate disk. An expandable element is introducible into the inner hole of at least two superimposed substrates. The element is expandable to such an extent that it can come into contact with the inner holes of both of the substrates to close off an intermediate space formed between the substrates relative to the environment. A substrate support is rotatable about an axis of rotation perpendicular to a support surface thereof. A centering device is rotatably coupled with the substrate support and is movable relative thereto in the direction of the axis of rotation. The expandable element is disposed, and is compressible, between the substrate support and the centering device.
